Connect to the official Open Data portal of the CNMC (Comisión Nacional de los Mercados y la Competencia). This server allows AI agents to explore and extract public data regarding telecommunications, energy, transport, and postal sectors in Spain.

What you can do

  • Catalog Discovery — Use package_search to find datasets, resources, and metadata using keywords or specific queries.
  • Data Extraction — Use datastore_search to pull actual records and rows from specific resources using their unique IDs.
  • Granular Filtering — Apply JSON filters to narrow down results to specific dates, regions, or categories within a dataset.
  • Resource Inspection — Identify update frequencies, license types, and resource formats before processing data.

How it works

  1. Subscribe to this server
  2. Enter your CNMC API Key (if required for higher rate limits)
  3. Start querying Spanish market data from Claude, Cursor, or any MCP-compatible client

Who is this for?

Search for datasets related to 'energía eléctrica' in the CNMC catalog.

I found several datasets. The most relevant one is 'Estadística mensual de energía eléctrica' with resource ID 'e123-abc'. Would you like me to fetch the latest records from it?

Get the first 5 records from the CNMC resource '06935639-5561-4608-9580-59367208479e'.

I've retrieved the first 5 records for that resource. They include data on market shares for telecommunications operators in Q1 2023. [Data table displayed...]

Search for 'gas natural' datasets and filter the results for the year 2022.

I've identified the 'Consumo de gas natural' dataset. Applying the filter for 2022... I found 12 monthly records. Would you like a summary of the total consumption?

Use the `package_search` tool with a query related to your topic. The response will include a list of resources, each with a unique `id` (the resource_id) that you can then use in `datastore_search`.
